The Android Market is a store for Android apps located on your Android smartphone. Some Android applications are paid apps, which means you'll need to have a payment method on file to purchase, download and install apps that have a price tag. If you have a payment method registered already and simply wish to change it to another debit card, you can do so quickly.

Start the Android Market application on your Android phone.

Open the "Apps" section and tap on any paid app, even if you don't want to buy it.

Tap the price button at the top of the app's detail page, and then tap on the payment method drop-down box.

Tap the "Add card" option.

Enter your debit card information into the provided fields. When finished, tap the "Save" button. This saves your new debit card information as a payment method, but it does not buy the application. You can then back out of the Android Market without making a purchase.
